Description

Double-sided tricot knitted fabrics for blanket having a bristle length of 10mm or more and a method for manufacturing the same

The present invention relates to a double-sided tricot warp knitted fabric for bedding and a method for manufacturing the same, and more specifically, using a microfine yarn as the yarn, and controlling the conditions during the process such as heat treatment temperature, raising properties, emulsion concentration and dyeing process. Side) Bedding with long pile raising of 10 mm or more manufactured using microfiber polyester improved to form a raised file with a length of 10 mm or more and a back file of 1 mm on the back side It relates to a double-sided tricot warp knitted fabric for use and a method for manufacturing the same.

In general, products with high piles (meaning Velour) are made using acrylic and circular knitting machines. These velor files are 10 to 25 mm long and have a rich voluminous feel, which has the advantage that they can be manufactured with a variety of tactile sensations, and are mainly used for toy dolls or artificial fur decorations for clothing.

However, the quality of the product is determined in the knitting process, the volume is large, so the burden of transportation costs is increased, and there is a problem that there is a limit in post-processing ability, as well as problems such as the file comes out easily due to friction. have. In addition, the daily productivity is 300 yds/day, which has a disadvantage in that the productivity is very low compared to the tricot warp knitting machine.

On the other hand, when a high pile product is knitted with a tricot warp knitting machine, the length of the pile is relatively short (3~10mm) compared to a high pile product made with a circular knitting machine, but the transportation cost is low, and there is no limit to the post-processing ability, so more various effects can be produced. Not only that, but the pile does not fall out even during friction or tension, and the productivity is 2000 yds/day, which is much higher than the high pile product made with a circular knitting machine.

The velor knitted by the conventional tricot warp knitting technique as described above has been mainly produced by a 3-bar warp knitting machine. This manufacturing method is a technique of forming a pile by knitting abrasive tissue with L1 and L2 bars, forming a loop with L3 bars, raising and cutting the loops. Mostly, since polyester of general fineness is used as yarn for both paper tissue and pile yarn, a filament of about 2 denier forms a pile, and a polyester filament of 2 denier has a bending stiffness that is enough to stand a pile in the vertical direction to the paper tissue. , so it stands in a uniform direction with respect to the branch.

However, when manufacturing a velor with the conventional tricot warp knitting technique, the back shogging distance of the L3 bar is mainly limited to about 6-7 needle pitch, so the length of the pile forming the loop is formed relatively short. At this time, if you want to increase the length of the pile, the technical limit of increasing the skipping interval is presented as a problem, and since the bending rigidity of the pile yarn itself used is large, the rough feel is felt even when the length of the pile is increased. There is a problem that it is difficult to expect a good effect.

In addition, it can be seen that on the surface of the velor knitted by the conventional warp knitting technique, the file stands stiff in a uniform direction, the cross-section of the raised and cut polyester yarn is rough, and the length of the cut fiber is not constant. Therefore, the velor knitted by the conventional warp knitting technique has a slight metallic luster due to the pile in a certain direction, and has a rough touch due to the non-uniformity of the cross-section of the cut polyester yarn and the stiffness of the yarn itself.

As described above, velor knitted by conventional warp knitting technology has been limited to a pile length of 1 to 2 mm, and for high pile products with a pile length of 3 to 10 mm, a pattern wheel for high pile production is already provided by the warp knitting machine manufacturer. However, there is a problem in that the wear of the machine increases due to the excessive skipping interval.

In addition, the biggest problem when knitting velor with the conventional warp knitting technique is that the file has a problem of shape instability due to long floating on the surface of the abrasive tissue.

As a result of Tables 2 and 3, it can be seen that all samples have excellent fastness, and the color difference is also less than 1.0 and uniformly dyed.

In addition, the K / S values of the samples prepared in Table 1 were measured, and the results are as shown in FIGS. 5 to 6 , and FIG. 5 is a sample No. It is a graph showing the result of measuring the K/S value of 1, and FIG. 6 is a sample No. 2 is a graph showing the result of measuring the K/S value, and FIG. 7 is sample No. It is a graph showing the result of measuring the K/S value of 3.

As a result of the analysis through the K/S measurement of the three samples, it was confirmed that they had K/S values of almost the same pattern as shown in FIGS. 5 to 7 , and the difference was also insignificant, and it was difficult to distinguish even with the naked eye. It is judged that color reproducibility can be secured without too much strain when applied in the field, and as a result, as can be seen from the results shown in Tables 2 to 3 and Figs. was able to confirm that

At this time, considering that the K/S value is a pile material, the front and back sides were measured respectively and comparative analysis was carried out respectively. To ensure reliability, a graph was prepared based on the average value after measuring CCM 5 times.

In the present invention, the wash dimensional change rate and tensile elongation for the prepared samples in Table 1 were additionally analyzed, and the pile length was measured to confirm whether the long pile, which is the biggest object of the present invention, was secured. The results are shown in Table 4 below.

division Black Gray Pink File length (mm) 10.5 11.0 11.6 Dimensional change rate (%) Length -0.5 -1.0 -0.5 width +0.5 +0.5 +0.5 Tensile Elongation (%) Length 29.0 31.4 31.0 pole 124.5 136.9 128.3

As a result of Table 3, it was confirmed that all pile lengths of 10mm or more were secured, and the dimensional change rate was also ±1.0% or less, so it was confirmed that there was no difficulty in applying it as a product. In addition, in order to apply the developed material as a blanket, it is desirable to secure the elongation at 130% or less. As a result, it was also found that the Pink and Black Samples except for Gray secured the low elongation of 130% or less.

In the present invention, detection of harmful substances and heat retention of the prepared sample were also tested, and the results are shown in Table 5 below.

division Black Gray Pink Formaldehyde detection (mg/kg) not detected not detected not detected Insulation rate (%) 61.9 62.4 63.0

As a result of Table 5, the content of formaldehyde was measured by analysis for the detection of harmful substances. As a result, formaldehyde was not detected in all three types of prototypes, and the detection limit at this time was 20 mg/kg. .

As a result of the thermal insulation rate, it was confirmed that all three types secured an exceptionally excellent thermal insulation rate.
